Problems solved by technology

[0005] The purpose of the present invention is to solve the technical problems of poor miscibility and poor emulsification of vegetable oils by using vegetable oil instead of benzene homologues (toluene, xylene, mixed benzene) to solve the problems caused by the use of benzene homologues. Environmentally friendly pesticide adjuvant based on vegetable oil, cosolvent and surfactant

Effect test

Embodiment 1

[0019] Embodiment 1 prepares 48% chlorpyrifos emulsifiable concentrate with pine oil

[0020] Get 310Kg of pine oil, 30Kg of calcium dodecylbenzenesulfonate, 20Kg of polyoxyethylene ether of alkylphenol formaldehyde resin, and 20Kg of polyoxyethylene ether of phenethylphenol polyoxyethylene ether in a reaction kettle and mix them evenly, and then mix the chlorpyrifos with a content of 98% 612Kg is put into the reaction kettle, and after mixing and stirring at a rotating speed of 180-200 rpm, 1 ton of homogeneous transparent oily preparation is obtained. The anti-decomposition and anti-freezing properties of the preparation meet the requirements of heat storage and cold storage tests, and a stable emulsion can be formed by adding water.

Embodiment 2

[0021] Embodiment 2 prepares 2.5% lambda-cyhalothrin (Kung Fu) emulsifiable concentrate with tea seed oil

[0022] Get tea seed oil 864.5Kg, fatty alcohol polyoxyethylene ether 30Kg, alkylphenol polyoxyethylene ether 20Kg, castor oil polyoxyethylene ether 20Kg and mix uniformly in reactor, then content 98% beta-cyhalothrin ( Kungfu) 25.5Kg of the original drug, after dissolving with dimethylformamide 30Kg, put it into the reactor, mix and stir evenly to obtain 1 ton of homogeneous transparent oily preparation. This preparation is a high-efficiency preparation specially used for preventing and treating the green leafhopper. Because it uses tea seed oil as an auxiliary agent and contains nutrients for the growth of tea trees, it can promote the growth of the tea trees while preventing and controlling the green leafhoppers.

Embodiment 3

[0023] Embodiment 3 prepares 3% acetamiprid tank mix with rapeseed oil

[0024] Formula: acetamiprid (active ingredient) 3%, ethanol 10%, rapeseed oil 80%, fatty alcohol polyoxyethylene ether 4%, castor oil polyoxyethylene ether 3%.

[0025] Preparation: After dissolving acetamiprid with ethanol, put it into rapeseed oil, mix it with fatty alcohol polyoxyethylene ether and castor oil polyoxyethylene ether, and spray it with water according to the concentration required by the control objects, for the control of wheat and rapeseed , Vegetable aphids, because rapeseed oil contains brassinolide can promote growth.

Description

technical field [0001] The invention relates to a pesticide, in particular to an environment-friendly pesticide adjuvant which takes vegetable oil, cosolvent and surfactant as raw materials. Background technique [0002] There are many existing pesticide preparation processing enterprises. In pesticide preparations, pesticide adjuvants are widely used, and the most widely used liquid preparations use benzene homologues (toluene, xylene, mixed benzene) as adjuvants. As we all know, the homologues of benzene (toluene, xylene, mixed benzene) are strong carcinogens identified by the World Health Organization, and are the largest pathogenic source of aplastic anemia (leukemia) and fetal congenital defects. Benzene homologues (toluene, xylene, mixed benzene) are flammable and explosive chemical hazards with low flash point and explosive concentration, which are very dangerous during the processing, storage and transportation of pesticide preparations. Simultaneously the homologue...
